Automatic splicing method for realizing multi-station simultaneous measurement in three-dimensional deformation monitoring of total station

Abstract

The invention discloses an automatic splicing method for realizing multi-station simultaneous measurement in three-dimensional deformation monitoring of a total station, wherein a conventional base is replaced by a photoelectric induction type base, and high-precision measurement is completed through automatic rotation of induction laser. The method can be used for multi-station splicing during precise control measurement or triangulation height measurement automatic monitoring or artificial networking, the prism does not need to be rotated manually, the same prism avoids errors caused by prism center inconsistency when double-face measurement is carried out through a double-head prism, high-precision measurement results can be obtained, the method can be widely used for splicing data of multiple observation stations, such as long-line subway protection area monitoring and large-range site three-dimensional deformation monitoring.

technical field [0001] The application relates to the technical field of total station monitoring, in particular to an automatic splicing method for realizing multi-station joint measurement in three-dimensional deformation monitoring of total stations. Background technique [0002] When using a high-precision total station for long-distance or large-scale three-dimensional deformation monitoring, if multi-station joint measurement is required, it is necessary to solve the splicing problem between the stations. The conventional solution is as follows: For example, multiple total stations in one When the orientation of the prism can be aimed at the prism, each total station is aimed at the same prism for measurement, and the prism points are used as common points for splicing. However, due to the limitation of the incident angle of the laser, and certain measurement errors, in practice Often the applicability is limited; connecting the measuring stations in series by laying w...

Problems solved by technology

[0002] When using a high-precision total station for long-distance or large-scale three-dimensional deformation monitoring, if multi-station joint measurement is required, it is necessary to solve the splicing problem between the stations. The conventional solution is as follows: For example, multiple total stations in one When the orientation of the prism can be aimed at the prism, each total station is aimed at the same prism for measurement, and the prism points are used as common points for splicing. However, due to the limitation of the incident angle of the laser, and certain measurement errors, in practice Often the applicability is limited; connecting the measuring stations in series by laying wire routes, this method has a large workload, and there are many sources of measurement errors, which will have a certain impact on the accuracy of the measurement results; Affected by the manufacturing error of the double-sided prism, the centers of the two prisms may not completely coincide. Even if the forced fitting is carried out by wire measurement, a certain error will be brought about

[0003] In the traditional measurement mode, the prism lens can only face one side during the measurement process. If you want to measure in other directions, you need to manually turn the prism lens to the direction to be measured, which will increase the workload and cause errors.
